From: Paul Burton Date: Fri, 14 Feb 2014 09:27:15 +0000 (+0000) Subject: MIPS: CPC: provide functions to retrieve register addresses X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2ba60250b01bfbab6b2293f8c1492312eb6a4131;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git MIPS: CPC: provide functions to retrieve register addresses This patch introduces addr_ functions in addition to the existing read_ & write_ functions. The new functions simply return the address of the appropriate CPC register rather than performing a memory access. This will be used in a subsequent patch.
